Description
The Rab Downpour Jacket is a lightweight and versatile waterproof jacket designed for hiking, trekking, and outdoor activities where the balance between protection, weight, and packability is essential. Constructed with Pertex® Shield membrane and recycled fabric, it offers an excellent combination of waterproofing, breathability, and comfort for regular mountain use.
Within the Rab range, the Downpour Jacket represents one of the most versatile and accessible options for users who need a reliable shell for rain, wind, and changing weather without venturing into heavier or more technical mountaineering constructions.
Its lightweight and easily compressible design allows it to always be carried in a backpack as a safety layer, making it particularly suitable for hiking, multi-day trekking, outdoor trips, and summer alpine getaways.
Real Technical Performance
In real use, the Rab Downpour Jacket stands out for offering very reliable protection against persistent rain while maintaining a contained weight and excellent overall comfort.
The Pertex® Shield membrane provides a good combination of waterproofing and moisture wicking, performing especially well during moderate activity or continuous trekking.
Compared to ultra-minimalist waterproofs, the Downpour conveys a sense of greater robustness and protection without excessively penalizing weight.

Comparison within the Rab range
Rab Downpour Mountain Jacket
The Downpour Mountain Jacket offers a more robust and technical construction for alpine trekking and more demanding mountain use. The Downpour Jacket prioritizes lightness, simplicity, and overall versatility.
Rab Firewall Jacket
The Firewall is clearly a step above in technical protection, resistance, and intensive use in serious mountaineering. The Downpour is lighter, more compact, and more accessible.
Rab Phantom Jacket
The Phantom is focused on extreme minimalism and fast & light activities. Much lighter and more compact, but less robust and less comfortable for prolonged use.
Rab Kangri GTX Jacket
The Kangri GTX belongs to the premium category of robust hardshells with 3-layer GORE‑TEX. Much more protective and resistant, although also heavier and more specialized.
Recommended use
- Hiking
- Light and medium trekking
- Outdoor travel
- Mountain getaways
- Emergency protection in backpack
- Outdoor activities with variable weather
